XWOS integrates the Lua language — a lightweight, compact scripting language. The port of Lua in XWOS is called <strong>XWLUA</strong>. <strong>XWLUA</strong> has the following features:</p> <ul> <li>Interactive REPL: an independent thread, users can run Lua functions online through a serial terminal, or run scripts in the file system;</li> <li>Multithreading: Lua does not natively support multithreading. XWLUA extends Lua to implement multithreading functionality;</li> <li>Lock mechanisms: supports mutex, spinlock, and seqlock;</li> <li>Synchronization mechanisms: supports semaphore, condition variable, event flag, signal selector, and thread barrier;</li> <li>Driver library: encapsulation of some drivers has been completed. <ul> <li>GPIO</li> <li>I2C</li> <li>SPI</li> <li>UART</li> </ul> </li> </ul> <figure class="card rounded p-2 td-post-card mb-4 mt-4" style="max-width: 780px"> <img class="card-img-top" src="/en/Docs/TechRefManual/Lua/xwlua-repl_hu5063848350667976902.png" width="770" height="623"> <figcaption class="card-body px-0 pt-2 pb-0 text-center"> <p class="card-text"> XWLUA interactive REPL </p>
